json - How to save a csv File using fast-csv that every attribute is in OWN column

Question

So I tried this example:

var csv = require("fast-csv");
    var fs = require("fs");
    var csvStream = csv.createWriteStream({ headers: true }),
        writableStream = fs.createWriteStream("my.csv");

    writableStream.on("finish", function () {
        console.log("DONE!");
    });

    csvStream.pipe(writableStream);
    csvStream.write({ a: "a0", b: "b0" });
    csvStream.write({ a: "a1", b: "b1" });
    csvStream.write({ a: "a2", b: "b2" });
    csvStream.end();

And I get this output:

But I want this output:

Is it possible that the values of a object are in another columns using fast-csv? Or is there another way that it is possible?
